[Parser] Parse folded instructions that contain parentheses (#6196)

To parse folded instructions in the right order, we need to defer parsing each
instruction until we have parsed each of its children and found its closing
parenthesis. Previously we naively looked for parentheses to determine where
instructions began and ended before we parsed them, but that scheme did not
correctly handle instructions that can contain parentheses in their immediates,
such as call_indirect.

Fix the problem by using the actual instruction parser functions with a
placeholder context to find the end of the instructions, including any kind of
immediates they might have.
